JavaScript

JavaScript is a programming language that was introduced by Netscape. It is a scripting language that places an emphasis on prototypes. Most people have encountered Javascript when visiting websites on the internet. However, it is used for a number of other applications as well. It can provide scripting access to objects that reside within various software programs. When many people first hear of JavaScript, they believe that it is a variation of Java. However, there are few similarities between these two languages. The primary thing they have in common are their connections to the syntax that is used in C.

Even though the trademark for JavaScript is held by Sun Microsystems, it was actually created by Netscape. Netscape used JavaScript with the Netscape Navigator web browser. It was first released at the end of 1995. However, JavaScript is also used with Internet Explorer in a version that is called JScript. As of this writing, the latest version of JavaScript is 1.7. JavaScript is a programming language that does not have constructs that are connected to either input or output. It uses the JavaScript engine to deal with these issues. The JavaScript engine will be dependent on what is called a host environment.

One of the primary uses for JavaScript is the creation of functions that are housed within HTML pages. These functions will make a connection with the DOM, or Document Object Model. They will carry out processes that HTML cannot carry out. One example of JavaScript is pop up windows that allow the user to control the size and look of the interface. JavaScript is also used to review a web form to make sure they are correct before sending them to the server. This will always take place within a given period of time. JavaScript is also responsible for the changes that occur in images when the mouse cursor is moved over them.

Many website designers find this to be an impressive feature, because it allows them to highlight important links or buttons. This feature is commonly called the “rollover” effect. It can be used with a number of different browsers, and CSS can be used to implement it as well. In addition to being a visually impressive feature, it can also be used to help people who may have vision problems. JavaScript also offers support to a large number of browsers that may not be compliant with the standards that are set in place by W3C. This is useful for cell phones, browsers that don’t support JavaScript, and those who have JavaScript disabled.

JavaScript is also used in situations where calls need to be made to web servers once a page has successfully loaded. These calls can be used to gather new data, and JavaScript can connect to the DOM of the page. In addition to the web, JavaScript is also used with PDF files and Adobe Acrobat. Mozilla is also known for using JavaScript to for the transaction logic of a number of different elements. It has become one of the most well known programming languages in existence today.
